loadData={loadData} /> ``` 通过异步加载功能,我们可以轻松地处理大型树形数据,并且能够实现按需加载,提升性能和用户体验。 6. 节点自定义操作 除了节点的显示和加载,有时我们还需要在节点上进行一些自定义的操作,比如右键菜单、拖拽排序等。在a-tree-select中,我们可以通过antd的Tree组件提供的一些事件和API来实...

loadData是Ant Design Tree组件中一个重要的属性,用于异步加载树节点的子节点数据。通常情况下,当我们使用树形结构展示大量数据时,数据可能无法一次性加载完毕,这时就可以使用loadData来实现按需加载。 loadData接受一个回调函数作为参数,在这个回调函数中我们可以根据不同的节点数据获取子节点数据。回调函数必须返回一个Pr...

Generally, data aggregation tree concept is used to find an energy efficient solution. However, even the best aggregation tree does not share the load of data packets to the transmitting nodes fairly while it is consuming the lowest possible energy of the network. Therefore, after some rounds, ...
1.若节点本身存在children,展开的这个节点不触发loadData方法,这样会让一些已存在children的节点无法异步加载数据。我之前用3.6.4版本时,每次展开节点均会触发loadData,而自己使用if(treeNode.props.children){}或者添加节点变量if(treeNode.props.refData.isLoad)这种方式来控制是否真正执行loadData(){}中的逻辑。
The simulation and comparison with other algorithms show that our TCBDGA can significantly balance the load of the whole network, reduce the energy consumption, alleviate the hotspot problem, and prolong the network lifetime. 展开 关键词: wireless sensor networks data gathering scheme cluster mobile ...
